According to the startup manual:

default: which is the default server environment that is started when no server environment is specified. It contains all except clustering and RMI/IIOP service.

all: contains all available services

However, when I looked into ~/conf and ~/deploy directory respectively, I find that the other than clustering and RMI/IIOP service, it contain JBoss.NET, jbossweb-ejb.jar and JacORB. What is jbossweb-ejb.jar? And why don't the startup manual mention these service?
